Arduino programming?

Question

how it is

Answer 1

It's basically C++ with standard libraries for accessing hardware devices.
Also, you don't define a main() function, but rather two functions, one is setup() which is called once to setup your program, and another one called loop() which is called continuously in an endless loop.
And the filename extension is .ino, not .cpp.
